Sprinkler and fire-protection work is not priced in this estimate.
Editorial planning model, not a supplier quote. All amounts are USD, including Canada. Excludes taxes, freight, slab remediation, electrical, HVAC, and unusual seismic work. The displayed permit / extra engineering allowance is a 1–3% assumption, not a local fee schedule. Confirm project-specific scope and pricing with qualified suppliers.
Methodology — where these numbers come from
Published guides provide broad context, with different dates and scopes. They do not validate this model's individual rates. Safety Source (2026) gives a $50–150 per-square-foot project range. Speedrack West (2025) repeats a roughly $70 benchmark attributed to 2024. Allied Modular (2025) gives a $40–$250+ range and explains that its low end can cover bare materials. Those ranges are not interchangeable installed quotes.
All rates and adjustments below are editorial planning assumptions, not published load-specific price lists or Cogan quotes. The model has not been calibrated against completed project quotes. Standard structural design is included in the structure allowance; the separate 1–3% line is a provisional allowance for permits and additional project engineering. Actual municipal fees and engineering services must be scoped separately.
Base structure, standard deck and installation (USD per sq ft)

|---|---|---|
| 125 psf | $52 | $72 |
| 150 psf | $58 | $80 |
| 200 psf | $68 | $95 |
| 250 psf | $80 | $115 |

How to reproduce the estimate
- Add the decking adjustment to the base rate. Multiply by the type, region and area-band factors, then by floor area.
- Add stairs, gates and your entered fire-protection allowance.
- Add 1% to the low subtotal and 3% to the high subtotal for the provisional permit / additional engineering allowance.
Area bands apply to the whole deck and create price steps at band boundaries. They are a coarse planning approximation, not a supplier discount schedule. All amounts remain USD, including Canada.
We do not use a fixed sprinkler percentage. The 35–40% figure cited by Speedrack West traces to a Premier Mezzanines article (2023) discussing UK structural fire protection, including column cladding and ceilings. It is not evidence for a US sprinkler-installation allowance. Use a contractor's project-specific figure.

Frequently asked questions
How much does a mezzanine cost per square foot in 2026?
Safety Source's 2026 guide gives a broad project range of $50–150 per square foot. That is context, not a quote or a validated rate for every load class. This calculator uses the editorial assumptions listed below, with exclusions shown beside the result.
What does this calculator include and exclude?
The model covers structure, decking, standard installation, the selected stairs and gates, and a 1–3% editorial allowance for permits and additional engineering. Fire protection is included only when you enter an allowance. Taxes, freight, slab remediation, electrical, HVAC, and unusual seismic work are excluded.
How does the calculator price sprinkler and fire-protection work?
It does not assign an automatic percentage. Enter a project-specific contractor allowance in USD to add that amount to both ends of the range before the permit / additional engineering allowance. A blank field excludes this work; it does not mean the work is unnecessary or free.
Is a rack-supported mezzanine cheaper than free-standing?
This model applies a 0.85 multiplier to the structure-and-deck rate for rack-supported designs. That is an editorial comparison assumption, not a guaranteed saving. Compare supplier quotes with the same area, load, access, and installation scope.
How accurate is a mezzanine cost calculator?
This model has not been calibrated against a representative set of completed project quotes, so no accuracy percentage is claimed. Use it to explore budget assumptions and compare itemized supplier quotes for your actual site.
Are Canadian estimates in Canadian dollars?
No. Every amount is in US dollars, including the Canada scenario. The regional multiplier changes the modeled cost; it is not an exchange-rate conversion.
